  • n. Any element from group 15 of the periodic table; nitrogen, phosphorus, arsenic, antimony and bismuth.


From Ancient Greek πνίγειν (pnigein, "to choke, to stifle") (a property of nitrogen) + -gen, with -t- in some forms, perhaps by analogy with pnictide. (Wiktionary)


  • The terms pnictogen and chalcogen are dear to my heart, yet they are just pretentious ways of saying nitrogen family and oxygen family.

    Annoying and pretentious terms.
